This procedure performs a TPMS (Tire Pressure Monitoring System) relearn on a 2021-2024 Ford F-150 to synchronize tire pressure sensor data with the vehicle's computer after tire rotation, sensor replacement, or pressure adjustment.

Warnings

Tools required

Preparation

1. Park vehicle on level ground and engage parking brake
2. Ensure ignition is OFF
3. Verify all four tire pressure sensors are functioning (no physical damage to valve stems)
4. Check and adjust all tire pressures to specification on door jamb placard (typically 35 PSI front and rear for F-150, but verify)
5. Locate OBD-II port under driver's side dashboard if using OBD-II relearn tool

Procedure

1. 1

   Verify tire pressures
   Use tire pressure gauge to confirm all four tires (plus spare if equipped with TPMS) are inflated to the pressure specified on the driver's door jamb placard. Adjust as needed with air compressor. Cold tire pressure is preferred for accuracy.
2. 2

   Turn ignition to ON position
   Insert key and turn ignition to ON position without starting the engine (or press Start button twice without pressing brake pedal). Verify instrument cluster illuminates and TPMS warning light is visible.
3. 3

   Access TPMS training mode via instrument cluster
   Using the steering wheel controls, navigate to the Settings menu on the instrument cluster display. Select 'Vehicle' > 'Tire Pressure Monitor System' > 'Train Tire Sensors'. The horn will chirp once and the TPMS light will flash to confirm training mode is active.
4. 4

   Train left front tire sensor
   Starting with the left front tire, place the TPMS relearn tool against the tire sidewall near the valve stem. Activate the tool to trigger the sensor. The horn will chirp when the sensor is successfully recognized. If using an OBD-II tool, follow the on-screen prompts to activate each sensor in sequence.
5. 5

   Train right front tire sensor
   Move to the right front tire and repeat the activation process with the TPMS relearn tool against the sidewall near the valve stem. Wait for the horn chirp confirmation before proceeding to the next tire.
6. 6

   Train right rear tire sensor
   Move to the right rear tire and activate the sensor using the TPMS relearn tool. Wait for horn chirp confirmation. The sequence must follow left front, right front, right rear, left rear for proper registration.
7. 7

   Train left rear tire sensor
   Move to the left rear tire and activate the final sensor with the TPMS relearn tool. The horn will chirp twice after this final sensor to indicate successful completion of the relearn procedure.
8. 8

   Exit training mode and verify
   Turn ignition OFF, then restart the engine. Observe the instrument cluster TPMS warning light. It should illuminate briefly during startup, then extinguish within 20 seconds. If the light remains on or flashes, repeat the relearn procedure.

Reassembly

1. No reassembly required for this procedure

Verification

• Start engine and verify TPMS warning light extinguishes after initial bulb check (approximately 5-20 seconds)
• Drive vehicle above 20 MPH for at least 2 minutes to allow system to fully initialize
• Check instrument cluster display to confirm all four tire pressure readings are displayed and accurate
• If TPMS light remains illuminated or flashing, verify tire pressures are correct and repeat relearn procedure
• If relearn continues to fail, check for damaged sensors or low sensor batteries (typically 5-7 year lifespan)
